Lock Out Tag Out – LoTo procedures to increase the safety of your employees

Constructing machines to be safe is an obligation. Procedures for safe maintenance, repairs, servicing and cleaning are discretionary. LoTo stands for Lock Out – Tag Out.

In essence, a machine remains potentially dangerous even when shut down. For instance, if a user starts the machine up while the machine is being maintained, a potentially life-threatening situation can arise. To prevent this, a machine can be rendered powerless using the LoTo procedure to ensure no further risk of movement. This ensures the safety of your maintenance and repair personnel at all times.

Does your machine have a lockable main electrical switch? Excellent! But what about pressure accumulators in hydraulic and pneumatic systems? What about kinetic energy? Are acids, alkalis or other hazardous substances present in your machine? Is there a risk of explosion or risk of chemical reactions such as if cleaning with the wrong tool?

To ensure all hazards are excluded and all necessary work on systems can be performed safelyLoTo procedures can be very useful. Furthermore, these procedures also provide much needed assistance in the form of training documentation for instructing new staff members.

Are you unfamiliar with LoTo procedures? We would be happy to assist you or to take care of creating LoTo procedures for you.
